| 摘 要： | 以室内土柱试验为基本研究手段,研究磷石膏对土壤物理、化学性状及养分的影响。结果表明,0.45%～0.6%磷石膏处理后,土壤的渗透性、pH值、全盐等特性都得到明显改善。因而,磷石膏可用于滨海盐碱土改良。

| Abstract: | In this paper, with the indoors soil column experiments as basic research means, the effects of PG on soil physical properties, chemical properties and nutrition were investigated. The results show that： with 0.3% -0.45% PG treatment, soil permeability, pH, total salt and other features have been significantly improved. PG could ameliorate coastal saline and alkaline soil effectively. |
